Simulators have been around for a long time. First, there were interpreters in the ‘80s and ‘90s, and despite being relatively slow, they were a big step up from fabricating the design and hoping it worked. However, as designs continued to increase in size, the interpreters could not keep up with simulation needs, and innovation was required for simulators to keep pace with new technology. This gave rise to the compiled code simulators in the mid-‘90s, which worked well enough for most people’s simulation needs. However, designs continued their non-linear growth, and yet again, innovation in simulator technology was needed to keep up.

The Xcelium Parallel Simulator is that innovation—the first simulator optimized for multi-core processing.
